[NEED HELP] with vaio replacement motherboard

Hello everyone,

I recently had to replace the motherboard of my vaio laptop due to a chipset failure. However, now my “Machine Name” and “Serial Number” shows as Reserved.
Is there any way to restore these to the original values? Asking because I cannot use the vaio restore function anymore. Can install a standalone version of windows 7 but would like to use the restore partition instead.

Model: VPCCA1C5E

Thanks
